What Happens if You Put Vinyl Over Aluminum Siding?
Metals are prone to corrosion and rust. Aluminum is no exception. Especially when they are exposed to moisture and water. Thus, you should not put vinyl over aluminum siding.
Vinyl siding, when put over aluminum will trap water. This overtime will corrode through the siding and onto the frame.

Why is Painting Aluminum Siding an Alternative to Vinyl Siding?
Although aluminum has attractive qualities, they are susceptible to dents.
Therefore to cover those flaws, painting is a great option. And it is a fairly easy job and anyone with a steady head and brush can do it.
Why do people stick to repainting, when they can replace it?
Painting can add extra life to the sidings as a protective layer. Moreover, can help prevent rust and corrosion.
Another reason why people stick to painting is the cost. Vinyl sidings are very expensive. The installation for a 1,500 sq. ft. home can range from $4,658 to $5,795. This, compared to a typical aluminum siding paint job, is pretty high.
Vinyl is less weather-resistant. Thus, it’s brittle and might crack in extreme weather. This can disrupt insulation.
